Introduction
In this article, I’ll take you all the way through all the parts of a stock trade, from start to finish. I’ve had a number of questions in email recently about aspects of stock trades that I’ll cover here, and it strikes me that a lot of people may not have a handle on the total picture. As a result, I think a lot of beginning traders skip or confuse some important steps.
Even if you’ve been trading a while, it might be fun to read through the stages I outline, and see if you can identify similar steps in your trading. If some are missing for you, or are just aspects of a trade that you “play by ear,” then that is a possible opportunity for improvement and growth. I hope this helps some people out. I’ll keep the discussion broad enough that I feel it covers most trading styles.
The Watchlist
Before you can trade at all, you have to be looking at stocks. Which stocks you look at is up to you… just put some thought into it and have a plan of some sort. Maybe you trade stocks for companies you know. Maybe you specialize in a sector. Maybe you watch the most actives. Maybe you use a real-time market scanner to watch the entire market. Might I humbly suggest you take a glance at my stock market scans?
One guideline is in order, though. The shorter the timeframe you want to trade, the more liquidity (think: volume) you are going to want. Especially if you are a day trader, you need lots of shares to be changing hands so that you can get in and out without too much slippage. I’ve seen books say day traders want stocks that trade at least 300,000 shares a day. I think that’s a terribly low figure, considering how many good stocks trade more than a million shares a day. Stick with the million plus stocks.
The Setup
Ok, so you’re watching stocks, but what are you looking for? The setup is the context for a possible trade. In general, you should know what kinds of conditions are best suited for your trading style. Here are a couple example setups:
- Stock is making a new 30 day high/low after a five day bounce (this is the setup that my daily scan here watches for)
- Stock is trending up, and is above its 8, 20, and 50-day EMAs. Also, the 8 EMA is above the 20 EMA, and the 20 EMA is above the 50 EMA. This is the kind of setup advocated in Short-Term Trading in the New Stock Market, for example.
Setups can be as complicated and explicit as you like. I personally use several more criteria on top of that first example when trading that type of setup. For instance, I like to see unusually strong volume, and no significant nearby resistance, and a similar looking move across the stock’s sector, etc. I am very demanding, which is why I only traded about 16 times in August. That’s perfectly okay… you don’t have to trade every single day to make a living.
Entry/Exit Criteria
Alright, one of your stocks is setting up nicely. Time to trade, right? Not at all. A good setup just grabs your attention… before you trade, you have to identify a good entry point. In fact, many good setups will not produce a trade at all, because there was no good entry available. So, let’s talk about what makes a good entry point.
The entry criteria for most traders are simpler than the setup criteria. Remember, if a stock has set up, it’s already basically doing what you want it to do. At that point, all most traders want is a good risk:reward place to get into a stock. Ironically, this means that the quality of the entry point is almost completely determined by the location of the worst-case exit point, or the stop loss price. In general, traders are looking for stops very close to their entry, since this produces better potential risk:reward ratios. To learn more about what risk:reward ratio is right for your trading, check out my article on that very topic.
Here are a couple examples of entry criteria:
- The stock has just broken the high of a narrow, inside 30 minute bar. The stop will be just below the low of that narrow bar. This makes for a nice, tight stop. It must also be early enough in the day that the stock has room to run at least 2 to 3 times that far in our favor. This is what I think of as the dummy trading entry criteria, though I may be oversimplifying.
- The stock has broken through resistance on high volume, and that resistance has become support after a drop back to that level on low volume. The stop will be just below the new support line, once the stock has started a new upward move. This makes for a very tight stop, which leads to good risk:reward characteristics.
There are a number of reasons to chose a stop prior to making the trade. First and foremost, it defines the risk side of the risk:reward ratio. Notice all the emphasis on finding a tight stop in the criteria above? Secondly, it’s harder to think rationally about your stop once you are in the trade. Therefore, it’s best to chose it beforehand, and only move the stop in your favor once the trade is on. Third, as we will see below, the stop value plays an important role in choosing your position size.
While I think it’s crucial to most trading styles to define your risk at this point, I’m a lot less adamant about chosing a profit target. Some traders do, and some don’t. All good traders have a clue about their risk:reward possibilities, though, so you want to at least determine that you think the stock could reach a good risk:reward profit amount. But, whether you choose a strict target or just decide the stock has enough room to run is a personal choice (or perhaps a trading system choice). A lot of traders–myself included–prefer to pick soft profit targets, and monitor the tape to get out early at possible market turning points.
Incidentally, many traders refer to their initial risk as “R,” and talk about their results in terms of multiples of this amount. For example, if my stop is 20 cents below my entry, and I am stopped out, then I say I have a -1 R trade since I have lost my full initial risk. If instead I make a 40 cent profit, then I have made 2 R, since I have made twice my initial risk. Sometimes we also refer to the dollar amount that we risk, or the percent of our equity that we risk, as “R.” When you think about it, it is all just different ways of saying the same thing. I like the cents-per-share characterization, because it makes it easy to calculate what price represents a 3 R gain in a trade, for example.
Choose a Position Size
Since you know where your stop is by now, choosing a position size should be easy if you know how much money you want to risk on the trade. For instance, if your stop is 10 cents away from your entry, and you want to risk $300, then you can buy 300 / 0.10 = 3000 shares. Simple division.
How do you know how much you want to risk, per trade? It’s a personal choice, but I generally suggest you always risk a fixed percent (I prefer 1% or less) of your current equity. So, if you have a $30k account, at 1% you’d want to risk $300 on each trade. I update my risk amount every $1000 dollars. So, say the example account grows to $31k. I’d start risking $310 per trade. Or, if a losing streak takes it down to $29k, I’d start risking $290 per trade.
For a more detailed explanation of the reasoning behind risking a percent of your current account size, you might want to read my article on choosing the right amount to risk, per trade, to fit your personality.
Now for a bit of a digression: About once every couple weeks, I get an email saying “Why pick a stop and then determine position size? I’d rather pick a position size, and let that determine my stop.” In other words, for example, a trader might like to always trade 1000 shares, or maybe they always buy as many shares as they can afford. Taking the 1000 share example, then knowing they want to risk $300, they can determine their stop location. They should put their stop 300 / 1000 = 30 cents below their entry, in that case.
It seems lots of beginning traders like this “size-first” idea, perhaps because they don’t like it when the “stop-first” method tells them to buy only 150 shares. However, I think the “size-first” method is inferior in just about every way. Why? Because if you let position size determine your stop, then your stop will be in an arbitrary location on the chart. Think about it: why would you wait long, excrutiating hours for precise setup and entry criteria to materialize, and then throw out a stop wherever it happens to fall? Doesn’t sound right, does it?
For just about any trading style, you want to the stop to be at a price that would invalidate your criteria for entry. So, if you are trading a break of resistance, then the stop should be a healthy amount below that resistance. That way, if you are stopped out, it is because the break you were playing didn’t hold. It makes sense to get out when the trade is no longer good, right? It’s also very easy to obey a stop that signifies a misbehaving stock. Don’t underestimate that benefit!
Consider if you took that same break-of-resistance trade “size-first”, and your position size says your stop should be 12 cents below entry. If that 12 cents happens to be above or at the resistance point, you will be stopped out with a much higher probability. Your win rate would suffer. Worse, an arbitrary stop invites you to ignore or move it when a trade goes against you. Since that 12 cent example stop has no meaning, you might convince yourself that the stock could turn around if given a little more wiggle room. This happens to traders all the time, and they end up pulling their stops. Many of those traders do not end up trading much longer.
Make the Trade
This is the moment you’ve been waiting for! Put an order in the market, and get in the action! Some traders get in all at once, while others scale into trades across several orders. Do whatever fits your system and your personality best, and do factor in the increased overhead cost of multiple orders if you go that way.
I generally use market orders, because I am trading very liquid stocks, and I want the fastest fill possible. Many traders prefer limit orders, which is also fine. Do whatever works for you, but do it fast: you’ve been waiting so long for the perfect opportunity, it’d be a shame to let it get away.
Here again, I can give a few guidelines. There are two ways to use limit orders. One way is to try to get a slightly better price for the stock. So you buy with a limit at or below the bid (alternately, sell at or above the ask). You can get away with this if the stock price is wiggling around a bunch, but not really moving in a direction. You take a small risk of not getting filled, but you’ll get a slightly better price this way (especially if the bid/ask spread is more than a couple cents). I rarely do this, because the setups I trade tend to produce fast movement.
The other way to use a limit order is to avoid getting filled at a bad price. In a fast-moving stock, issuing a market order can mean a fill 10 cents or more away from your desired entry. To avoid this, you buy with a limit a couple cents above the ask (or sell a few cents below the bid). With this kind of limit, you will either get filled at an acceptable price, or not at all. I’ve seen people get confused and ask why you would ever pay more than the ask, but recall that a limit order gets filled at the limit or better.
Trade Management
As with the watchlist step, there’s not much I can say here, except “have a plan.” If you picked a hard profit target in the previous steps, then your trade management is simple: exit at your profit target, or your stop, whichever is hit first. Other styles will require more active monitoring to determine exits. Some traders will scale out of trades, while others get out all at once. As with entry, do whatever fits you and your system best.
I have to take this opportunity to say one more time: obey your stop. If you only do one thing right, let it be that. If you obey your stops (and you risk a reasonable amount per trade), you will have time to fix just about anything else you are doing wrong. It’s by pulling stops that traders end up losing their shirts (and houses, and spouses). What’s worse is when a trader tries pulling their stop, and the stock happens to turn around for big profits. Please don’t let that fool you.
Another good rule of thumb, which may not be applicable to all trading styles, is: don’t let a profit turn into a loss. This doesn’t mean you should move your stop to break-even if the stock moves one cent in your favor. That’s too extreme. But, protecting some of your profit once you have made a healthy amount is usually a good idea. Many traders chose to move up their stops when they hit 1 R of profit, for example.
Record-Keeping for Stock Trades
Other than obeying your stop (have I mentioned that, yet?), this is probably the most important aspect of a trade. A certain amount of record-keeping is mandatory to do your taxes properly, but that’s not really the kind of information that I’m referring to here.
It’s simple, really: obeying your stops gives you time to improve, and detailed records give you the data you need to improve. What are good details to keep? On top of the normal entry/exit/profit, I suggest a combination of:
- Whatever detail is relevant to your trading style. Ideally, you should be able to look at the information you’ve saved off, and decide all over again whether you would enter the same trade today. So, if you trade MA crossovers, then save off a chart that has the MAs on them. If you trade broken resistance, save off a chart that shows where you thought the resistance was.
- The overall market context. Things like sector charts, or QQQQ/DIA/SPY charts, are good. This way you can review how the overall market impacts your trading system. It can also tell you whether a market turn did you in (or, alternately, saved you!), or if it was an aspect of your system’s criteria that was bad.
- Your thought process during the trade. Write a paragraph about what you were thinking before, during, and after the trade. Try to write this ASAP (I do this just after the market close whenever possible). After a week or so, you will be able to objectively review what you were thinking, and identify errors in your judgement.
I focused above on finding errors and mistakes, but you can also review and reward yourself for trades gone well. Or, even when trades are good, you might be able to spot ways to make them better.
This record-keeping process can be tedious. At StockTickr, a service I use and contribute to, we are doing what we can to automate collecting this data and facilitating R-based performance review. You can see that here when I review my trades and performance… all those charts are collected and annotated automatically for me, as well as reference charts of the indices for that day. It’s a big time-saver. We’re also adding a number of reports that let you see your performance over time from different perspectives.
Besides per-trade records, I also suggest keeping a record on the side of anything that bothers you, or makes you especially happy. You don’t like getting up so early? Write it down. The biotech stocks you are trading are too jittery for your nerves? Make a note of it. As I described in this article, you can use these notes to shape a trading plan that fits your personality better. Sometimes, you don’t know what kind of trader you are until you actually jump in and try it. By noting what you like and don’t like, you can periodically review and improve your trading “lifestyle.”
Summary
Trading is a little more involved than “buy low, sell high.” Here, I’ve tried to outline all the steps that are part of just about any stock trade. I’ve also tried to give some guidelines and rules of thumb, without making the article too specific to any one trading style. It is my hope that traders (especially new ones) go through this list, and identify the aspects of their trading that fit these stages. Making sure all your bases are covered will give you a leg up on the majority of amateur traders out there.
